There were topics on this issue but they’re now closed yet the problem still remains and is very annoying and making it difficult to use the browser to such an extent that I think I will have to change it.
When there are tabs opened in group, and if I close all pages except one, this one remains as part of a group. Well I don’t need a group anymore if there’s only one page in it! It takes up unnecessary space. It should ungroup/remove last tab from the group automatically.
And it worked that way long time ago, but then, a bug crept in that was not fixed by subsequent updates.
